Given numbers are 270,663,390,131
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 270,663,390,131 is 7816770.
Find LCM of 270,663,390,131 with Prime Factorization
2 | 270, 663, 390, 131 |
3 | 135, 663, 195, 131 |
5 | 45, 221, 65, 131 |
13 | 9, 221, 13, 131 |
9, 17, 1, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 9 x 17 x 1 x 131 = 7816770
Therefore, the lowest common multiple of 270,663,390,131 is 7816770.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
270 x 663 x 390 x 131 = 9145620900
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270
663 : 1, 3, 13, 17, 39, 51, 221, 663
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
131 : 1, 131
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 270,663,390,131, is 1.
Now, the common factors can be found like this.
270:2x 3x 3x 3x 5
663:3x 13x 17
390:2x 3x 5x 13
131:131
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5x 13 = 1170
Therefore, the value for common factors is 1170.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 9145620900/(1x1170)
LCM = 9145620900/1170
LCM = 7816770
Thus, we can understand that the LCM of 270,663,390,131 is 7816770.
